Armstrong and Aldrin landed their spacecraft, the Eagle, in an area of the Moon called the Sea of Tranquillity and explored the surface for more than two hours.

Project Apollo, the United States's manned Moon landing programme, culminated in 1969 with Apollo 11. Mission commander Neil Armstrong's famous words, "That's one small step for man, one giant leap for mankind", spoken as he stepped onto the lunar surface, were heard by an estimated 600 million television viewers. This clip contains some re-enactment footage.
Meet the men who landed on the Moon.

James May meets Apollo astronaut Charlie Duke. From mission control in Houston, Duke was in direct communication with the Apollo 11 astronauts inside the landing craft, Eagle. He later walked on the Moon during the Apollo 16 mission.
Apollo scientists find that Newton didn't get it exactly right.
Although Newton's Law of Universal Gravitation is a good approximation of gravity, more precise measurements of the Moon's orbit show it is not a perfect explanation.
Buzz Aldrin (born Edwin Eugene Aldrin Jr.; January 20, 1930) is an American engineer and former astronaut, and the second person to walk on the Moon.
